+Yes, fresh install using the Mageia 2 beta 1 netinstall ISO, I selected

+Well if I press Ctrl-Alt-F2 after waiting 10-15 seconds after the screen 
+goes into standby during boot, I still don't get the a video signal 
+back. I can then press Ctrl-Alt-Del and the system will shut down 
+cleanly so it's not frozen, it's only the video output that doesn't 
+work with Mageia.
